,To all whom/ it may concern:

Be it known that we, WILLIAM O. KOETZ- NER, residing at Baltimore, inthe State of Maryland, and JOHN J. KOETZNER, residing at Washington, inthe District of Columbia, citizens of thfeLl-InitedmStates, haveinvented certain new and useful Improvements in Floor- PolishingBrushes; and we do declare the fol-I lowing to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had 'to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

Our invention relates to improvements in floor-polishing brushes; andthe object is to overcome the many objections now met with by thoseskilled in the art of Waxing and polishing floors, dro., as is wellknown, and there fore to produce a brush for waxing and polishingfioors, dac. but also applicable for other purposes; also to arrange thebrush in such manner that it can be used as a hand-brush,

or with a long handle, when in upright position; also that it may beused with adjustable weights, easily applied or detached, and to suitthe strengthof weak or strong persons; also to readily apply or detachthe long handle, and provide it with a friction-roller, arranged in suchmanner as to be'out of the center, thereby causing the face of the brushto remain in a horizontal position, and thus cause it to wear equal oreven on its face, avoiding the'uneven surfaces in wax-floors now usuallyproduced; furthermore, to facilitate the throwing of the brush from oneto the other side of the room, by loosening the handle and pivoting it;also to produce means for polishing the floor after it has been waxed byapplying fibrous material over the `bris-` tles, and finally to preventinjury to the wash-i` boards, dre., by scratching or bumping bythe sidesof the brush coming in contact there with.

Vith these objects in view our invention consists in the peculiarconstruction of cer tain details and the arrangement of parts, as willbe more fully described hereinafter, and

specifically pointed out in the claims, reference beinghad to theaccompanying drawings, and the letters of reference marked thereon.

Like letters indicate similar parts in the different figures of thedrawings, in which Figure l represents a top view of our improved brush.Fig. 2 is a side elevation` of the same, partly in section. spectiveview thereof with the weights removed and the long handle attached.Fig.. 4c is a detail view of a plate with pins for securing the fibrousmaterial in perspective, partly broken. Fig. 5 is a modification ofattaching the operating-handle. tail sectional view of anothermodification for securing the handle. Fig. 7 is a modification of theshort handle.

In the accompanying drawings, A represents the main body of the brush,in which the bristles are secured in the ordinary manner. It can be madeof any size and material desired, and is secured to a metal plate B,having the short handle O, which is provided with a slot b,in each endof which are placed the rubber cushions c, to prevent jarring, inthrowing the brush from one side to the other of a room.` Said handlehas at each end shoulders d, serving to hold the weights steady whenapplied in place. This handle O serves to use the brush with the hand,when in a kneeling or stooping position.

lf it is desired to use the brush by a person in an upright position, along handle D is applied in the following manner: An eye e is providedwith the two plates or ears f, forming a forked end, which passes overthe upper part of' the short handle O and carries a frictionroller orpulley E, loosely fitting into slot h. It facilitates the movements 0fthe handle in its forward and backward motion, when loosely pivoted, asdescribed farther on. In

the ears f are provided a series of holes g, and

in the short handle O are similar holes g. Two springs F, pivoted to thebolt h, which serves also to secure the long handle to the ears f, areprovided with pins t', that will en ter either one of the sets of holesg and g', when said springs are turned downward, and thus ,f secure thehandle in fixed position, at a greater Fig. 3 is a perff Fig. 6 is a defw and held at each end by said pins j.

or lesser angle or centrally, to suit the circumstances. Then the brushis to be swung, or what is termed thrown from side to side, the springsF are turned downward by releasing the pins i'. from the holein thehandle D and are entered into one of the holes g', thus pivoting thebrush.

The plate B is provided at each end with a groove Z1' for the receptionof pins;- on the wei ght G and serves to hold a piece of fibrousmateriahsuch as carpet, flannel, or its equivalent,which passes over theface of the bristles in the brush, as shown in broken lines in Fig. 2,and serves for polishing the floor after it has been waxed, the carpetbein g clamped The weights G G are each provided with a rectan guiaropening 7c, (seen best in broken lines in Fig. 1,) so that they can bereadily placed over the shoulders d on the plate B. As many of theseplates or weights G G can be employed as desired. In the edge of thebody A a groove a is formed, into which a band of rubber II of circular,semicirculai-, or equivalent form is placed, to prevent the brush com.-in g in con tact with the washbcard, and thereby scratching or injuringit.

The handle D may be secured to the brush in the manner shown in Fig. o',in which the spring I having' a pin Z is secured to thehandle D by ascrew o, and a groove m is provided, and when the pin l, which engageswith a hole Z in the eye c, is pressed upon the spring is depressed intosaid groove, and the handle can be removed.

In the modification shown in Fig. 5 the short handle C consists of asquare or rectangular bar secured to the shoulders d with the cushionsc. A cross-head K iits over this bar C' and to itthe handle D isattached, and the brush can thus be thrown backward and forward.

The short handle C may be made detachable, as shown in Fig. 7.

ll'aving thus described our invention, what we claim, and desire tosecure by Letters Patent, is*- l. The floor-polishing brush described,consistin g of the brush A, provided with the handle C provided with theslot b, in which the roller E, secured to the springs F moves as and forthe purpose specied.

2. The floor-polishing brush described, consistin g of the brush A,provided with the handie C, provided with the slot Z) in combinationwith the handle D having springs F for adj usting it, and provided withthe roller E moving in said slot, and all arranged as shown and setforth.

In testimony whereof wc affix our signatures in presence of twowitnesses.
